If IPSec provides security at the network layer, why is it that security mechanisms are still needed at layers above IP?

Solution Preview: The first limitation is that it only provides coarse form policy management support, and takes the decision without the knowledge of application context (Arkko and Nikender 2005, p. 242). The policy selector of IPsec is composed of only tuple of source /destination addresses, port number and transport protocol type……

If IPSec provides security at the network layer, why is it that security mechanisms are still needed at layers above IP?

Question If IPSec provides security at the network layer, why is it that security mechanisms are still needed at layers above IP?

Answer

IPSec protects traffic across the Internet but once you’re connected to the corporate network, that traffic is in the clear. IPsec supports network-level peer authentication, data origin authentication, data purity, and data encryption. Therefore security mechanisms are still needed at layers above IP using IPsec as it help us get protected from : 1.Network-based attacks from untrusted computers. 2.Attacks that can result in the denial-of-service of applications. 3.Data corruption 4.Data theft 5.User-credential theft 6.Administrative control of network, computers, and server.
